JOHN SUTTON, OF NEW YORK, N. Y.

IMPROVEMENT IN CHIMNEY-TOPS.

Specification forming part of Letters Patent No. 192,308, dated June 19, 1877; application filed May 19, 1877.

To all whom it may concern Be it known that 1, JOHN SUTTON, of the city of New York, in the State of New York, have invented a new and useful Improve.- ment in Chimney Shafts or Tops, of which the following is a description, reference being had to the accompanying drawing, which forms part of this specification.

This invention relates to chimneys of dwelling-honses and other buildings having two or more flues; and consists in a novel construction of the shaft or upper portion of the chimney above the roof of its building, whereby the several fines are made to converge within the shaft, cap, or other upper portion of the chimney toward a common outlet, and a free and straightup draft is obtained for each fine, so that not only one chimney-pot, outletpipe, or cowl will answer for a number of fines, but the draft of one fine is not cut off or crossed by that of another, and each fine is made to assist the other, and the draft through the several fines is or may be equalized.

Figure 1 represents a vertical section of a chimney-shaft with a cap mounted thereon, and having my invention applied. Fig. 2 is also a vertical section of a chimney-shaft with cap and cowl mounted thereon, and my invention under another of its many modifications applied.

Referring, in the first instance, to Fig. l, A is the shaft or portion of the chimney proper above the roof, said shaft having a series of fines, b, formed by upright dividing brick walls 0, which stop short of the top of the shaft. From the tops of the dividing-walls c, and from opposite sides of the chimney-shaft, are run or extended metallic or other thin terminal flue dividers or conductors d, which proiect upward and. form reduced continuations of the walls of the fines. These reduced fluedividers d are bent, inclined, or otherwise made to converge toward the cap B as a common outlet, up within which said terminal flue-dividers may be more or less projected,

' which answers for the several fines, be arranged over the upper terminal portions of the fines as formed by the dividers d.

This construction provides for a large number of fines in the one chimney being arranged to converge toward a central and common outlet without any abrupt bend or angle, and so that the gaseous products of combustion escaping by any one of the fines wlll not be crossed or interfered with by the currents of the other fines, and an approximately equal draft may be obtained for all the flues, any tendency to increased draft in either one of the fines assisting the weaker drafts of the other fines. Furthermore, a free or full area is obtained for the fines, and a single cap, exit-pipe, or cowl of very moderate dimensions answers for all the fines, and there is less liability of the draft being impaired by wind or weather.

The invention may be applied alike to old as to new chimneys, and to both single and double stacks, and admits of various modifications or changes, according to the d mensions or peculiarities of the shaft or slze or kind of the cap or other outlet mounted thereon.

The modification shown in Fig.2 has the partition-walls 0 of the fines I) run up to the top of the shaft A, and the terminal fine-d1- viders d, which project upward from said walls, arranged wholly within and formed by the cap B; but the fines converge toward a central and common outlet, and with the same effects as in the modification first described.

By the construction, however, shown in Fig.

v1, in which the walls 0 of the flue stop short of the'top of the shaft A, a larger number of fines may be extended by the converg ng d1- viders cl up to or within the cap, exit-pipe or other chimney-outlet without materially 1ncreasing the size of the latter, and without making any abrupt angle or break in the terminal portions of the fines.

In some cases the terminal converging fluedividers d may be made in upper and lower sections, the upper sections being inthe cap, exit-pipe, cowl, or other top piece, and the lower sections in the chimney-shaft, and said two sections made to meet or match each other.

l. The combination, with the fine-dividing walls a in the shaft of the chimney, of the ter- 2 memos minal flue dividers or conductors (1, arranged converging terminal flue dividers or conductto extend upward from said walls and to conors d, of a lesser thickness than said walls, esverge toward or within a common outlet, subsentially as shown and described.

stantially as specified.
